Process for removing ozone-depleting and/or climate-active fluorinated compounds from a gas stream and application of the process

摘要

A process is provided for removing fluorinated compounds, such as perfluorinated or partially fluorinated C1 to C4 hydrocarbons, NF.sub. 3 and SF.sub.6, out of a gas by passing this gas through gamma alumina, wherein the temperature of the gamma alumina is between ambient temperature and 600 C. The gas stream and the gamma alumina are anhydrous. The fluorinated compounds chemically react with the gamma alumina to result in a gas containing a diminished quantity of fluorinated compounds and an aluminum fluoride containing composition.
